PATENT OFFICE.

srncinrcArroN forming part ofLetters Patent No. 284,271, dated septembera, `18:33. l Application filed May 16,` 1,88 (No model.) A

VTo all whom, it'` may concern.- Be it known that I, FITZROY K. BRIERLY,

ycitizen of the United States, residingat New Brighton, in the county of Beaver and `State of Pennsylvania, have invented certainnew and useful Improvementsin Coffee-Mills, of which .theV following is a specication, reference behad therein to the accompanying-`drawings.

Figure l` represents a top plan view of a coffee-mill to which my improvements have been applied. Fig. 2 is a front elevation of the mill, and Fig. 3 avertical section taken through `the line m of Fig. 1.

My invention relates to grinding-mills, it `being particularly' designed for reducing coffee; but it will be obvious that other substances may be ground therein.

`Myimprovement consists in the following `construction `and arrangement `of devices, which will be first fully described, and then y pointed out in the claims.

Referring to the drawings, A `represents the frame or box of the coffee-mill, and which `maybe of any desired construction.

It is'provided with the usual receiving-drawer, B, for the ground coffee. The hopper is formed from #the concave block H in the upper 'part of the mill, and the concavo-convex sections or `castings D and d, one of which, d, constitutes `placed in the hopper to be ground. (See Fig. l.) The stationary casting D is preferably `fastened to the frame A `by screws or bolts,

the screw a forming the hinge upon which the The vparts of the castings D d, Where the hinge is located, have overlap- .ping and underlapping extensions b c, as

shown by the drawings, the -impinging faces of which are inclined in such manner that when the lid turns upon the screw or bolt a in opening, the incline raises the cover in its pivotal movement from contact withithe top z ofthe box-frame A. In general,`the lids of coffee-mills of this class have had their hinge- Y joint screwed directly to the woodenbox-a jointwhich soon wears loose, rubbing the top of the box and marring the appearance of the coee-mill. On'tiie opposite side of the castings D .d from the extensions b c are other extensions, ef, cast with the castings. The latter receives the screw g, the head of which forms a catch, over which the depression in the under side of the extension f drops when the lid d is closed. The inclined extensions b c `of the hinge also prevent the tendency of the lid or cover d from coming open during the grinding movement ofthe mill. Through the apex of the casting D is pierced a hole, which receives theupper portion of the grindingshaft E. The crank-handle F has its bearing The lower walls of the hopper, as stated,- are formed from a block, H, jtted to the in terior of the frame A, and turned" out neatly into a saucer-shaped receptacle. lTo'tthe cen tral'bottom aperture of the block is itted the stationary grinding-shell I by bolts or screws Through this aperture passes or otherwise. the vertical grinding-shaft E, (adjustable, as

described,) to the lower end of which is fitted the rotary conical grinder J ,but it will be understood that any form of construction of grinding or reducing faces may be used.

4Nhenit is desiredto4 obtain access to the grinder or hopper, either for inspection, re-

pair, or renewal, the screws whichr secure mthe castings D d onlyhave to be removed, andthe nut Gr taken off, when the whole interior may be readily got at.

Having described my invention, what I claim l. In acoffee-mill, a hopper provided with a cover having an inclined pivotal hinge bearing, substantially as described, whereby the cover tends to remain closed during the grinding movement or agitation of the mill.

2. In a coffee-mill, the box A and castings D and d, each of which has an inclined face, y

` in combination with a screw or bolt, a, passas and for the purpose described. l

3. In a, coffee-mill,- the combination of the boX'A, screw' or bolt a, the screw g, and the 5 castings D and d, one of which7 D, is stationary, and has an inclined face-extension, c, and the other, d, being movable, and has aninelined ezgtens'ion, b, and a catch depression, whereby the movable portion d may form a ing through the inclined faces, substantially cover for the hopper, opening and closing asA Io described. y.
